Jami` at-Tirmidhi, Book 49, Hadith 4196 (In-Book) ⓘ
Narrated Ibn 'Umar: "I had a dream in which I saw as if there was a piece of silk in my hand, and I would not gesture to any place in Paradise except that it would fly with me, (taking me) to it. So I told the dream to Hafsah, so she told it to the Prophet, so he said: 'Indeed, your brother is a righteous man,' or 'Indeed, 'Abdullah is a righteous man.'"
حَدَّثَنَا أَحْمَدُ بْنُ مَنِيعٍ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ إِبْرَاهِيمَ، عَنْ أَيُّوبَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ رَأَيْتُ فِي الْمَنَامِ كَأَنَّمَا فِي يَدِي قِطْعَةُ إِسْتَبْرَقٍ وَلاَ أُشِيرُ بِهَا إِلَى مَوْضِعٍ مِنَ الْجَنَّةِ إِلاَّ طَارَتْ بِي إِلَيْهِ فَقَصَصْتُهَا عَلَى حَفْصَةَ فَقَصَّتْهَا حَفْصَةُ عَلَى النَّبِيِّ صلى الله عليه وسلم فَقَالَ " إِنَّ أَخَاكِ رَجُلٌ صَالِحٌ " . أَوْ " إِنَّ عَبْدَ اللَّهِ رَجُلٌ صَالِحٌ " . قَالَ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
